Knob (5) will turn on the laser sight only. The letter “B” will allow the user to turn on
both the laser sight and the red dot sight at the same time. After you are done using the
DLB140R, make sure that the Rheostat Knob is set to “0” in order to preserve battery
life.
ZEROING YOUR RED DOT SIGHT
ADJUSTING WINDAGE AND ELEVATION:
Your DLB140R is equipped with adjuster turrets for Windage and Elevation. The
Elevation Adjuster (8) is located on top of the Sight Tube (1). First remove the cap on the
Elevation Adjuster (8) and use a flat head screwdriver or thin coin to make adjustments.
Twisting the Elevation Adjuster (8) counter-clockwise move the red dot down, and
twisting the Elevation Adjuster (8) clockwise will move the dot up. Replace the cap once
you have made all necessary adjustments. The Windage Adjuster (7) is located on the
right side of the Sight Tube (1). First remove the cap on the Windage Adjuster (7) and
use a flat head screwdriver or thin coin to make adjustments. Twisting the Windage
Adjuster (7) counter-clockwise will move the red dot to the left, and twisting the
Windage Adjuster (7) clockwise will move the crosshairs to the right.
NOTE: Each click of adjustment changes the point of impact (where the bullet strikes the
target). This means that the makings on the Windage Adjuster (7) stating Æ L will
actually move the Red dot to the right. This also means that the markings on the
Elevation Adjuster (8) Æ UP will move the red dot down. Each click will move the red
dot by the amount shown on the chart below.
Windage/Elevation inches of movement per click

SIGHTING IN YOUR RED DOT SIGHT:
We recommend the use of a bore sighting device to save time and ammunition when
zeroing your sight. This device will help you get on paper much quicker. Follow all of
the instructions set by the manufacturer of your bore sighting device very carefully.
Once you have achieved a relative zero by way of bore sighting, it is still necessary to
shoot your firearm to ensure an accurate zero.
CAUTION: Always be sure to remove the bore sighting device before from your firearm
before shooting live ammunition. Failure to do so can result in damage to your firearm,
or injury to yourself and those around you.
With some firearms it may not be possible to use a bore sighting device. In this case it
will be necessary to use a more traditional method of zeroing.
